A city of 40000 residents has an average per capita water demand of 150 1/c/d. The average size of institutional and commercial areas is 200 ha and that of industrial areas is 100 ha. The expected unit water demands are 20 mº/ha/d for institutional and commercial areas, and 15 m/ha/d for industries. The public water demand and unaccounted for system losses are estimated to be 5 % and 15% of the total water demand, respectively. Calculate the total water demand, excluding fire flow.
